• Characterisation of the Halden silt 

      Blaker, Øyvind; Carroll, Roselyn; L'Heureux, Jean-Sébastien (Chapter, 2016)
      NGI recently established a research site on a natural silt deposit to accommodate some of the challenges related to intermediate soils. This study briefly summarises the geological history and the preliminary geotechnical ...

      Paniagua, P; L'Heureux, Jean-Sébastien; Carroll, Roselyn; Kåsin, Kristoffer; Sjursen, Morten Andreas; Amundsen, Helene A. (Chapter, 2017)
    • Factual report - Halden research site 

      Carroll, Roselyn; Blaker, Øyvind; Paniagua, Priscilla (NGI-rapport;20160154-04-R Rev. 1, Report, 2020-01-06)
      Halden silt site is property of Halden municipality and it is known locally as Rødsparken. As part of the characterization of Halden silt site during NGTS project, two main reports are prepared: 1) a factual report ...
    • Field experiments at three sites to investigate the effects of age on steel piles driven in sand 

      Carroll, Roselyn; Carotenuto, Pasquale; Dano, C.; Salama, I.; Silva, M.; Rimoy, S.; Gavin, K.; Jardine, R. (Peer reviewed; Journal article, 2019)
      This paper investigates the influences that steel type, in-situ soil properties, water table depth, pile diameter, roughness and driving procedures have on the ageing behaviour of piles driven in sand. Tension tests have ...
    • Halden research site: geotechnical characterization of a post glacial silt 

      Blaker, Øyvind; Carroll, Roselyn; Paniagua Lopez, Ana Priscilla; DeGroot, Don J.; L Heureux, Jean-Sebastien (Peer reviewed; Journal article, 2019)
      This paper describes the geology and geotechnical engineering properties of the Halden silt; a 10–12 m thick deposit of fjord-marine, low plasticity clayey silt. Over the last six years, the test site has been well ...
    • Monotonic and dilatory excess pore water dissipations in silt following CPTU at variable penetration rate 

      Paniagua López, Ana Priscilla; Carroll, Roselyn; L'Heureux, Jean-Sébastien; Nordal, Steinar (Chapter, 2016)
      The relationship between cone penetration rate and pore pressure decay is investigated through dissipation tests following penetration at different rates. Field tests and model scale tests in the laboratory are performed. ...
    • Norway's National GeoTest Site Research Infrastructure (NGTS) 

      L'Heureux, Jean-Sébastien; Lunne, Tom; Lacasse, Suzanne; Carroll, Roselyn; Strandvik, Stein Oddvar; Instanes, Arne; Sinitsyn, Anatoly; Degago, Samson Abate; Nordal, Steinar (Chapter, 2017)
    • Variable rate of penetration and dissipation test results in a natural silty soil 

      Carroll, Roselyn; Paniagua Lopez, Ana Priscilla (Chapter, 2018)
      Variable rate of penetration over 1.2 to 1.5 m intervals were carried out in a natural clayey silt followed by dissipation tests. The tests are grouped into two main sets: an upper set from 5 to 6.5 m and a deeper set from ...
